Description

[Detailed Description of the Invention] The present invention relates to a float structure in a rice transplanter.

In other words, in a rice transplanter configured to allow multi-row planting by arranging three or more floats in parallel,
Conventionally, when the machine moves forward to perform planting work, the water removed by the float suddenly flows into the path of the float, which has a negative effect on the planted seedlings in the vicinity.

The present invention solves this drawback by allowing water to quickly flow to the rear side of the float without losing its leveling effect, thereby softening the shock of rapid water flow against planted seedlings. The present invention provides a simple structure that can be suitably implemented.

Next, the embodiment shown in the drawings will be described.

Figure 1 shows a plan view of a riding rice transplanter, with both front wheels 4
The planting device B is connected to the rear via a link mechanism 8 so that it can be indexed by the traveling vehicle A, which is a four-wheeled vehicle having both rear wheels 5 and is equipped with a handle 6 and a seat 7. Both side floats 2a, 2 whose rear parts are longer rearward than the rear part of the central float 1 are installed on both sides of the central float 1 installed in the center float 1.
A seedling mounting stand 9 having five seedling mounting surfaces arranged diagonally at the front high and rear low across the top of each float.
is installed so that its lower part can reciprocate in the horizontal direction along a horizontally installed seedling take-out plate 10, and each of the five planting claws 11 is placed on both sides of the rear of both side floats 2a and 2b. Positions P, P and planting position P which is inside the recessed part 1a at the center of the rear part of the central float 1
It is constructed in the same way as the conventional structure, with seedlings planted in each.

Each float 1, 2 on the lateral side of each planting position P
Supports 12 for adjusting the planting depth and for connection are respectively fixed on the upper surfaces of the floats a and 2b, as in the conventional type, but for both side floats 2a and 2b,
The float rear part 3b at the rear of the support 12, which is on the lateral side of the planting position P, is formed to be lower and thinner than the front part 3a in front of it.

Therefore, when the floats 1, 2a, and 2b slide on the rice field and seedlings are planted at each planting position P by the planting claws 11 to perform rice planting in 5 rows, especially when water flows in, On the rear side of both side floats 2a and 2b, where the floats tend to move forward, the float rear part 3b, which has a low and thin wall, performs a leveling action as before, but because it is low and thin, water flows upward from the side while moving forward. It becomes a state of flowing,
This means that water can be quickly flowed to the center side behind the float, and the water does not suddenly flow into the path of the float as in the past.

As described above, the present invention provides a rice transplanter configured to allow multi-row planting by arranging three or more floats 1, 2a, 2b in parallel, from at least the vicinity of the planting position P of the side floats 2a, 2b. Since the rear part 3b of the float is formed to be lower and thinner than the front part 3a, water can flow into the rear part 3b of the float quickly without losing the leveling effect, making it easier to plant seedlings. It has the advantage of being able to soften the shock of rapid water flow, allowing for successful planting without adversely affecting planted seedlings unlike conventional methods, and having a simple structure that allows for convenient implementation. have

Claims (1)

[Scope of utility model registration request] In a rice transplanter configured to be able to perform multi-row planting by arranging three or more floats 1, 2a, 2b in parallel, at least a float rear part 3b which is rearward of the vicinity of the planting position P in the side floats 2a, 2b is provided. The float structure is characterized by being formed lower and thinner than the front part 3a.
